The versatility of the Unit system is best illustrated with the different ways of showing bent angles. You can build linear atoms with 2 polar or 2 radial pegs; 100 degree bent angle with a radial & tetrahedral peg; 110 degrees with 2 of the tetrahedral pegs or 120 degrees with 2 radial pegs.
Other angles are also possible with a bit of calculation.
